Adrenergic receptors are members of the G-protein coupled receptor superfamily. Recent studies revealed that these adrenergic receptors are playing an important role in the growth and metastasis of prostate cancer cells. The expression of adrenergic receptors rises significantly in prostate cancer cells and tissues. Agonists of these receptors promote the growth and mobility of prostate cancer cells, while antagonists may suppress their proliferation, trigger their apoptosis, and inhibit their metastasis. Clinically, receptor antagonists can significantly reduce the risk of prostate cancer and improve its prognosis after androgen depravation therapy. This article presents an overview on the roles of adrenergic receptors in prostate cancer.

BACKGROUND:There are many preliminary studies on the survival, metaptosis, and correlation characteristics of human amniotic epithelial cel s after transplanted into the animals, but there are no reports on the quantitative analysis of the transplantation effect. OBJECTIVE:To make quantitative analysis on serum biochemical function of liver and the expression of human albumin in mice received passaged human amniotic epithelial cel s transplantation in spleen. METHODS:Forty nude mice were randomly divided into four groups (n=10 in each group):hepatectomy+cel transplantation 2 weeks group, hepatectomy+cel transplantation 4 weeks group, hepatectomy+normal saline group (treated with partial hepatectomy) and hepatectomy+cel transplantation group (transplanted with 0.2 mL passaged human amniotic epithelial cel s with 5×106 under spleen, and the blood were col ected at 2 and 4 weeks after transplantation). The mice in the hepatectomy+normal saline group were treated with splenic injection of 0.2 mL normal saline;the cel transplantation group did not receive hepatectomy, and transplanted with 0.2 mL passaged human amniotic epithelial cel s with 5×106 under spleen. The histological and morphological changes of the liver and spleen in each group as wel as the expressions of serum alanine aminotransferase, aspartate aminotransferase and human serum albumin in each group were detected, and the quantitative analysis of human serum albumin expression was performed. RESULTS AND CONCLUSION: There was no obvious morphological change after human amniotic epithelial cel s transplanted into the acute liver injury mice for 4 weeks, but specific cel s could be detected by histological method. The serum levels of alanine aminotransferase, aspartate aminotransferase and human serum albumin were improved obviously, and the human albumin could be detected in serum, the level of human albumin at 4 weeks after transplantation was significantly increased than 2 weeks after transplantation. Human amniotic epithelial cel s can survive for more than 4 weeks after transplanted into the liver injury mice, and can stil express partial characteristics and functions of hepatocyte-like cel s, improve the liver function, thus treating acute liver injury.

Objective: To observe the effect of mild moxibustion on cancer-related fatigue, serum ghrelin and adiponectin in patients undergoing chemotherapy after colorectal cancer surgery. Methods: Seventy patients were divided into a control group and an observation group according to the random number table method, with 35 cases in each group. Patients in both groups were treated with conventional FOLFOX4 chemotherapy regimen. Patients in the control group also received routine treatments such as symptomatic treatment of complications, health education, nutritional support, and exercise intervention. Patients in the observation group received mild moxibustion on the basis of interventions used in the control group. The Piper fatigue scale-revision (PFS-R), Karnofsky performance status (KPS) and spleen and kidney yang deficiency syndrome were scored, and serum ghrelin and adiponectin levels were measured before and after treatment. Results: After treatment, total score of PFS-R in the control group did not change significantly (P>0.05), while in the observation group it was significantly reduced (P<0.05) and lower than that in the control group (P<0.05); KPS scores in both groups were increased (both P<0.05), and it was significantly higher in the observation group than in the control group (P<0.05); total score of spleen and kidney yang deficiency syndrome in the control group did not change significantly (P>0.05), while it was significantly reduced in the observation group (P<0.05) and lower than that in the control group (P<0.05); serum ghrelin and adiponectin levels in the control group had no significant changes (both P>0.05), but the levels were significantly increased in the observation group (both P<0.05) and higher than those in the control group (both P<0.05). Conclusion: Based on the routine treatments, mild moxibustion can relieve fatigue, improve quality of life, and improve the symptoms of spleen and kidney yang deficiency in patients undergoing chemotherapy after colorectal cancer surgery, which may be related to the regulation of serum ghrelin and adiponectin levels.
